We're infusing a 38ft center console hull in Tampa, FL. Our usual Derakane 510A vinyl ester is on a 3-week factory backorder. We need an immediate domestic substitute with viscosity < 200 cP and HDT > 215°F that won't print-through on marine gelcoat.
Analysis of Target Formulation & Infusion Kinetics:

Derakane 510A is a brominated epoxy-based vinyl ester resin. For high-speed commercial boat infusion where MIL-Spec brominated flame spread isn't mandated, you need a high-elongation Bisphenol-A vinyl ester with ultra-low peak exotherm to prevent post-cure print-through on ISO/NPG marine gelcoats.
